针对蒸汽供热系统控制对象多变量、大滞后等特点,将多变量控制和快速模糊控制结合起来,提出了多变量快速模糊控制,并进行了仿真。仿真结果表明这种方法的控制有效地解决了中压和低压供热蒸汽温度和压力控制问题。多变量协调模糊控制系统的成功投入,使蒸汽温度和压力的波动范围减小到原来的一半。
Aiming at the characteristics of multi-variable and large lag of the controlled objects of steam heating system, multivariable control and fast fuzzy control are combined. A multivariable fast fuzzy control is proposed and simulated. The simulation results show that the control of this method effectively solves the problem of temperature and pressure control of medium and low pressure heating steam. The successful investment of multivariable coordinated fuzzy control system can reduce the fluctuation range of steam temperature and pressure to half.
